Justin Poore has been warned over a tackle he made during Wakefield's win at Hull on Monday.
The Wildcats prop was put on report for a challenge on Shannon McDonnell as his side won 27-26 in East Yorkshire.
Hull coach Peter Gentle claimed after the game McDonnell was lucky to escape a serious back injury.
But the Rugby Football League's match-review panel decided the incident merited a caution rather than a charge.
And Australian Poore, who has been sent off twice in his first season in England, will be available for next week's game against Widnes.
